is there someone who knows what this back-end message refers to?
"Please enter a partner number"
After an upgrade from SRM-EBP 3.0 to SRM 5.0 Classic Scenario with ECC 6.0 like back-end, just with a particular Supplier this is the message shown by the system before the creation, from EBP sourcing cockpit, of the Purchase Order.
Does it refer to the Supplier? Really?
